Identify the vertex of a parabola in vertex form.
\( \text{Which of these is the correct vertex for } y = (x + 3)^2 + 2? \)
Select all correct options:
Read \(h\) and \(k\) from the formula; change the sign of h if inside the bracket it’s +.
The vertex of \(y = a(x-h)^2 + k\) is \((h,k)\); adjust the sign of h when needed.
